Saint, I personally believe that we are missing the point of the Gospel when we add "law" back into it. We were freed from the Law; it no longer condemns us. I think some people think that Paul is here reinstating a New Covenant Law of some kind, as if covering or not covering your head can be some act of righteousness in and of itself, rather than a symbol of a holy heart. That is heresy; that is Pharisaical Christianity, and is a rejection of the Gospel itself. When this sort of thing is taught on a denominational level (Boston Church of Christ, World Wide Church of God, each who teach the same as you on the issue of head coverings and consistantly legalistic on others), they are declared cults and rejected by orthodox Christianity. This can be a small thing that is fun to argue about or it can be a very big deal. Be careful how far you take this.
